title: A new species of Spirura Blanchard, 1849 (Nematoda: Spiruridae) parasite of Heliosciurus gambianus and Xerus erythropus (Rodentia: Sciuridae) in Senegal.
abstract: A new species of Spirura is described from the stomach of Heliosciurus gambianus and Xerus erythropus (Sciuridae). Considering the number of preanal papillae of males, Babero (1973 ) and Giannetto and Canestri Trotti (1995) proposed the subdivision of the genus into 2 groups; those with 4 pairs of preanal papillae (25 species) and with more than 4 pairs of preanal papillae (4 species). Spirura mounporti n. sp. belongs to the second, with 5 pairs of preanal papillae, and differs from Spirura infundibuliformis (McLeod, 1933) Anderson et al., 1993 , Spirura zapi ( Erickson, 1938 ) Chabaud et al., 1965 , Spirura leiperi Gupta and Trivedi, 1985, and Spirura michiganensis Sandground, 1935 in the number of pairs of pre-cloacal papillae. The new species further differs from other species of the genus in having 21 caudal papillae, in the ratio of spicules:body length, and in its morpho-anatomical characters.
